EBUNG FOR BARRELS.

moaeai. I

Application filed July 20,

To all wkoni it may concern.

Be it known that I, CHARLES L. HOOPER, a citizen of the United States,and resident of Rochester, in the county of Monroe and State of NewYork, have invented certain new and useful Improvements in Bungs forBarrels, of which the following is a specifieation.

The present invention relates to bungs for barrels, casks and the like,and an object thereof is to provide in connection with the bung asealing device which will prevent the removal of the bung except uponthe mutilation of the seal.-

To this and other ends the invention consists of certain parts andcombinations of parts all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

In the drawings: Fig. 1 is a face view of the bung without the seal; i

Fig. 2 is a similar'v'iew with the seal in place;

Fig. 3 is a plan View of the seal; Fig. 4 is a diametric section of theseal; Fig. 5 is a diametric section through the V seal,-the bung and thebung hole ring, the

tool for applying the seal being shown in dotted lines r Fig. 6 is aface View of another bung to which another embodiment of the inventionis applied;

Fig. 7 is a face view of the seal applied to the bung shown in Fig. 6;

Fig. 8 is a plan view of the seal before its application to the bung;and

Fig. 9 is a diametric section through the seal, the bung and the bunghole ring, showing th seal applied.

Referring more particularly to the drawings, 1 indicates a fragment of abarrel or cask, which in this instance is made of sheet metal and has abung hole formed in a ring or spud 2'secured to the cask, the walls ofthe bung hole being internally threaded. A bung 3 in the form of a plugwith external threads, engages the internal threads of the bung hole andis also provided with an annular flange 4 abutting the bottom of anannular groove or pocket 5 surrounding the bung hole. The bung is fittedin and Specification of Letters Patent.

removed from the bung hole through a wrench fitted into a non-circularpocket 6 formed in the outer face of the bung." This pocket issurrounded by an annular seat 7 which in turn is partially overhung byan overhanging portion 8 of circular form. The seal, before applicationto the bung, is in the form of a concavo-convex circular disk 9 asillustrated in Figs. 3 and 4, which may have its central-portionprovided with an advertisement or other suitable matter. In fitting theseal disk to the bung, it is inserted within the annular. overhangingportion 8 to rest against the seat '7 and the tool 10 illustrated indotted lines Fig. 5 is-so formed at its end that when hit with a blow itwill shape the disk in the manner illustrated in Fig. 5, driving theedge of the disk against the seat and under the overhanging portionwithout at the same time destroying the matter at the center of thedisk. It will be apparent that this disk will entirely 'cover the wrenchsocket 6 and will prevent the use of a wrench in the socket until thedisk is destroyed or mutilated.

In the embodiment of the invention shown in Figs. 6 to 9 inclusive, thebung hole ring 2 is the same as in the other embodiment. The bung 3differs ,from the bung of the other embodiment in having its pocket 6not surrounded by a seat and overhanging portion. The seal 9 is in theform of a disk with a ring shaped portion 9 connected thereto by a neckportion 9.

The disk portion 9 has a perforated ear 9 and the ring portion 9 has aprojecting perforated ear 9 The ring portion is fitted about the bung soas to lie between the flange at and the shoulder formed by the bottom ofthe annular groove or pocket 5. The connecting portion 9 extends aroundone edge of the flange 4 so that the disk portion 9 covers the socket 6The two perforated ears 9 and 9" are brought into overlapping relationand a. sealing device 11 formed of solder or other suitable material isthen introduced through the openings in the ears.

to hold the two ends of the seal together. It is apparent that thewrench cannot be introduced into the wrench socket 6* until the seal isbroken.

In both embodiments of the invention the pexternally threaded portionand providing a surrounding seat, the body being provided with a wrenchsocket opening at the outer face of the body and closed at the innerend, and a disk covering said wrench socket to prevent the use thereofexcept through the destruction of the disk.

2. A bung for barrels comprising a body having an externally threadedportion at the inner end and asurrounding flange at 20 the outer endproviding a seat about the body, the body also being provided with awrench socket in its outer face and closed at its inner end, and a seatat the outer end of the wrench socket, an-overhanging wall 25surrounding said seat, and a disk covering said wrench socketand restingagainst the seat under said overhanging wall.
